Tips:

This trail follows a creek and is VERY muddy in winter -- not recommended during wet weather. As an alternative, head up Quarry Road and take Quarry trail to the Round Top Loop trail.

You can download a interpretive park map from the East Bay Regional Park website before you head out. I recommend this as the trail heads are not always kept stocked with maps.

Be sure to check out the fascinating labyrinths constructed in the old quarry pits throughout the park. Sibley is full of surprises so take the time to explore along the way! less «
